Elastic Recovery Frequently Asked Questions
Short answers to the questions buyers ask most often about Elastic Recovery.
What does it mean?
how completely fabric returns after extension. Working figures for Elastic Recovery normally sit around above 90% after cycling in mainstream production. Note ISO 13934-1 recovery loop on the tech pack so nobody tests against an older revision.
What value should be specified?
Start from above 90% after cycling and adjust for the end use of the garment. Record elastane content alongside Elastic Recovery, because blends shift the measured value. A result outside above 90% after cycling usually points to process drift rather than to the fibre itself.

How is it tested?
ISO 13934-1 recovery loop. Keeping reference values for Elastic Recovery lets suppliers quote without extra sampling rounds. Ask for conditioning details together with ISO 13934-1 recovery loop, since both affect the reading.
Why does it change between lots?
Process variables such as finishing temperature and elastane batch cause the normal spread of results. Working figures for Elastic Recovery normally sit around above 90% after cycling in mainstream production. Note ISO 13934-1 recovery loop on the tech pack so nobody tests against an older revision.
Can results be compared across suppliers?
Only when the same standard revision and conditioning are used; otherwise measurements are not equivalent. Record elastane content alongside Elastic Recovery, because blends shift the measured value. A result outside above 90% after cycling usually points to process drift rather than to the fibre itself.
